Anonymous Access and Authentication Control

Sets the anonymous access and authentication control methods for access to the server. Click Edit to select one or more authentication methods from the following options:

Allow Anonymous Access – Check this box to allow anonymous users to log on to your web server. When a user establishes an anonymous connection, your server will log on to the user with an unknown or guest account, a valid Windows NT user account. Click Edit to specify which Windows NT User version to use for anonymous connections.

Basic Authentication – Check this box to enable your Web Server’s primary authentication method, where the password is sent in clear text. This option requires a username and password when the Allow Anonymous option is disabled or access to the server is controlled using NTFS Access Control Lists.

Windows NT Challenge/Response – Check this box to enable your Web server’s Windows NT Challenge/Response authentication methods. Basic authentication requires a username and password when the Allow Anonymous option is disabled or access to the server is controlled using NTFS Access control lists.
